Transfer A Phone Number From T-Mobile to Orange | PAC Codes

Switching from T-Mobile to Orange? It's a straightforward process to keep your existing phone number.

Step 1: Obtain a PAC Code from T-Mobile

The first step is to contact T-Mobile and to obtain your Porting Authorisation Code (PAC Code).

You can get a PAC Code from T-Mobile by calling 150 on your T-Mobile handset. Alternatively, dial 0845 412 5000 from any other phone (extra charges apply when calling from another network).

You can request a PAC Code over the phone at any time during T-Mobile's opening hours:

Monday - Friday8am - 10pm
Saturday - Sunday8am - 8pm

  • Your PAC Code will normally be issued immediately on the phone. We recommend having pen & paper ready.
  • T-Mobile must provide a PAC code within 2 hours of your request. If they don't, there must be a valid reason for why the PAC Code can't be issued. Your right to a PAC code is enshrined within Ofcom's "General Conditions of Entitlement" (December 2013, clause 18).
  • A PAC Code is 9 digits long and follows the format ABC 123 123.
  • Your PAC Code is valid for 30 days. If you don't use it in time, the code will expire and you'll need to request a new one.
  • You shouldn't close your account at T-Mobile: it'll end automatically when you give the PAC Code to Orange.

Step 2: Order the new phone or SIM card from Orange's website

You should now order your new phone or SIM card using the Orange website. Please select the type of tariff you're intending to move to:

Orange

For a full list of available tariffs and the latest Orange deals, please refer to this page on Orange's website.

Orange will assign you with a temporary phone number during the transition process.

Step 3: Give the PAC Code to Orange

Once your new phone or SIM card has arrived from Orange, switch it on and make sure everything's working properly. If you need to return or replace the new phone, please do this before the number transfer.

Once you're happy to continue with the number transfer, contact Orange and provide them with your PAC Code.

The PAC Code should be entered on Orange's online form. Alternatively, Pay Monthly customers can call 150 from their mobile (or 07973 100 150 from another phone). Pay As You Go customers should call 450 from their mobile (or 07973 100 150 from another phone). If you're going to call Orange, please be aware of their opening hours.

Providing your PAC Code to Orange

The PAC Code should be submitted through a form on Orange's website.

  • You must provide the PAC Code to Orange within 30 days of its issue. If the PAC Code has already expired, return to step 1 and request a new PAC Code from T-Mobile.
  • T-Mobile Pay As You Go customers: Try to use up any remaining credit - it can't be transferred to Orange.

Step 4: Phone Number Transferred (Next Working Day)

As long as you've submitted your PAC Code to Orange before 5.30pm, your phone number transfer will normally be scheduled for the next working day (Monday to Friday only, excluding UK bank holidays). After 5.30pm, you'll need to wait one extra working day for your number to be transferred.

On the day of the transfer, you'll momentarily lose coverage on both of your handsets. When this happens, restart your handset on Orange. You should find that the Orange phone or SIM card is now associated with your original phone number.

  • If you see an error message (e.g. "SIM card registration failed"), this means it's time to restart your phone.
  • Once the phone number has been transferred to Orange, your account on T-Mobile will automatically be closed. You'll receive a final bill for any outstanding charges.

    I think I may need to contact Orange customer support but just wanted to get some background in case.

    I have just switched from a T-mobile SIM only 30 day plan to an Orange pay monthly.

    I obtained the PAC from TM yesterday and gave it to Orange. I received a txt message from Orange on my OLD phone telling me that my settings had been updated and to turn my phone off and back on again this morning about 4am.

    Now, today, I can make outgoing calls and texts and the receipient gets my old number showing on their screens, however, incoming calls and messages are going to my old phone.

    The phone number that came with my Orange phone has been disconnected.

    Does this sound like the transfer is still in progress and I received the text too early? Or should I be concerned that there is a problem now?

    Any help, gratefully received.

      Hi Alan,

      It sounds as if your phone number transfer might still be in progress? My recommendation is to restart your phone every couple of hours – if there’s still a problem by the end of the working day then you should get in touch with Orange Customer Services (dial 150 from your Orange handset). Fingers crossed everything will work properly – do keep us updated on the status of your transfer!

    I gave my PAC code to Orange two weeks ago, a week later nothing happened. Rang them up a week ago and was told that it would be sorted by midnight, got a text on my old sim card from T-Mobile (my old network) saying that it had started the process and would be done by the end of the day. A week later, and again nothing has happened. So I rang them this morning to be told there was something wrong with my PAC code, so I re-gave them the code and was told it would be done between 11am and 3pm. It's now 5 and a half hours after this time and still nothing.

    Why is it taking so long? And is this actually against the law (Ofcom) as I have seen on some forums that there is a set amount of days that the network has to transfer the number over?
